[PVE-User] proxmox 5 - replication fails

[dorsy]

Another strange thing is that the failing jobs are running out of schedule.

Jul 12 12:00:03 ns pvesr[12049]: total estimated size is 119M
Jul 12 12:00:03 ns pvesr[12049]: TIME        SENT   SNAPSHOT
Jul 12 12:00:04 ns pvesr[12049]: 12:00:04   9.18M 
rpool/data/vm-100-disk-1 at __replicate_100-0_1499853601__
...
Jul 12 12:00:14 ns pvesr[12049]: 12:00:14    113M 
rpool/data/vm-100-disk-1 at __replicate_100-0_1499853601__

No errors in logs. Finishes just seemingly fine. Schedule is */2:00.

However after approx. 5 minutes it wants to send the whole disk:

Jul 12 12:06:03 ns pvesr[13511]: send from @ to 
rpool/data/vm-100-disk-1 at __replicate_100-0_1499853960__ estimated size 
is 8.64G


Is there any way to get more debug info from pvesr or the scheduling of 
the replication?
